Where Can I Buy A Hot Surface Ignitor

Ensuring the right amount of voltage is applied to the HSI keeps it functioning. Too much voltage and the HSI and the control board can break. Too little voltage and the ignitor might not burn hot enough.

where can i buy a hot surface ignitor

In a gas furnace, natural gas or propane is used to ignite a flame inside the burner. This flame heats up the metal heat exchanger, which moves heat into your home. Your ductwork carries the warm air throughout your home and colder air is returned to the furnace where it repeats the heating cycle.

Hot surface ignitors are a more recent invention. They are made of a resistant element like silicon nitride or silicon carbide with wires attached to the ignitor. Voltage is applied to the wires, causing the element to heat in a minute or less. Hot surface ignitors last anywhere from five to ten years before needing to be replaced.

A furnace ignitor replacement costs $100 to $250 on average. Most universal hot-surface ignitor prices are $15 to $35 for the part alone. Gas furnace ignitor prices are $20 to $100 for parts from the original manufacturer (OEM). The labor cost to replace a heater ignitor is $80 to $200.

Universal hot-surface ignitor prices are $15 to $35 on average or up to $100 for OEM or original equipment manufacturer parts. A new furnace spark ignitor costs $20 to $50 for the part alone.

A furnace ignitor lasts 3 to 7 years on average. For furnaces over 7 years old, ask the contractor to replace the ignitor and flame sensor to prevent an emergency fix later. Most furnaces outlast their ignitor parts.

Hot surface ignitor are the most commonly used electronic ignition system. It works like a light bulb filament, heating up when electricity is passed through it. Most are made from silicon nitride or silicon carbide ceramic. When the gas valve opens, the gas is ignited by the igniter.

Silicon nitride ceramic hot surface ignitor are PTC ceramic elements: PTC ceramic materials are named for their positive thermal coefficient of resistance (i.e., resistance increases upon heating). That mean that they have a highly nonlinear thermal response, so that above a composition-dependent threshold temperature their resistance increases rapidly. This behavior causes the material to act as its own thermostat, since current passes when it is cool, and does not when it is too hot, so the temperature stabilize at a certain tempereture (11001400C).

If the ignitor stays on for an extended period of time this will make the ignitor short-lived. Most of the time when ignitors go bad that often it is because the ignitor is not shutting off after the gas in the furnace is ignited. If the ignitor stays on for an extended period of time this will make the ignitor short-lived.Also the highest is the surface temperature (depend on voltage applied), the shorter the lifespan will be.

However contrary to silicon carbide ceramic hot surface ignitor which are very brittle and shouldn't be touched, silicon nitride hot surface ignitor are very robust and can be cleaned manually iff really necessary. If you can disassemble the igniter from appliance, clean the surface with a the toothbrush or dry cloth and do not use detergent. Make sure that the main power is off when cleaning the surface of the ignitor.

Insert the straw taped to the side of the can of compressed air into the nozzle of the can. Hold the can upright 12 inches from the ceramic ignitor. Tap the release button on the can to send a few short bursts of air onto the ignitor to clean away any dust.

The two composition materials generally associated with hot surface igniters are silicon carbide and silicon nitride. Silicon carbide is a compound of carbon and silicon and is characterized by a low density and oxidation resistance.

It can seem like your Furnace goes out when you need it most. Even with preventive maintenance, your Furnace can misbehave on the coldest days of the year. Sometimes it's a quick fix. In other cases, you could have a faulty furnace ignitor.

Today, the furnace igniter replaces the open flame of the pilot light in most furnaces. Without the ignitor, your heater won't blow hot air. It's a critical part of your furnace system and one of the most common reasons your Furnace doesn't work correctly.

You've probably heard the "click" from your Furnace before the air starts blowing. When the thermostat kicks on to start the Furnace, the ignitor creates a spark that "ignites" the gas connected to your heater. Other types of igniters heat without a spark. Instead, these ignitors heat up and touch the surface of the gas to heat the air blowing from the Furnace.

Take a look at the switch that controls the power to your Furnace. If the furnace breaker is "on," there could be an issue with the ignitor, or you could have a more significant electrical problem.

Your Furnace has built-in fail-safes to keep you and your house safe when there is a problem with the system. If you enjoy the warm air from your Furnace, but it suddenly stops blowing, that could indicate a sudden problem with the ignitor.

If your furnace goes on and off frequently, the ignitor could be the culprit. An ignitor on its way out can't hold a charge long enough to heat the furnace air. Plus, your Furnace probably has a safety feature that forces your system to wait at least 60 seconds before it starts again.

Repeatedly tripping the breaker is terrible for your Furnace and your home's electrical system. While a faulty furnace ignitor can be a simple fix, don't let the Furnace continue to trip the breaker more than twice. Leave the breaker set to "off" while repairing the furnace problem.

That "click" we mentioned earlier is the sound of your ignitor trying to warm the fuel in your Furnace. However, if you hear the click but the air doesn't blow soon, you could have a dangerous ignitor problem.

You can expect gas furnace ignitors to handle a 120 volt electric supply from the household circuit. This electricity allows the ignitor to create a spark or heat the silicon to generate a flame. Fluctuations in this optimum range can be dangerous and cause the ignitor to short circuit.

You'll need to know what the ignitor looks like to make sure you don't mess with the wrong parts inside your Furnace. After removing the burner panel door from the Furnace, look for a small device connected between the electrical wires and the Furnace near the gas input.

Most furnace ignitors last about seven years. The lifespan of your furnace ignitor will depend partly on how well maintained your system is. Regularly changing furnace filters and scheduling yearly technician maintenance is key to getting the most out of your ignitor.

The furnace ignitor is what creates the small spark needed to heat the air coming from the Furnace. Without that spark, the Furnace can only circulate air that's being brought in from outside, whatever temperature that may be.

On average, furnace ignitors will last about four to seven years. This depends upon how well maintained the system is. After the seven-year mark, you should replace it. The Furnace itself can easily last you for 20 years or more with proper maintenance.

At the first signs of a faulty furnace ignitor, take action. Investigate the symptoms on your own, then call a professional to handle a repair. An ignitor repair or replacement is often an inexpensive fix that can save you from more significant (and expensive) furnace repairs. A professional repair can also protect you from injury or accident.

Hot surface igniters are a resistance element made of silicon carbide or silicon nitride. Anywhere from 80 to 240 volts are applied to the wires attached to the igniter. A ceramic base insulates the wire connection to the carbide element which looks like the letter M on most applications. Spirals are another shape I see. Most nitride igniters are formed in the shape of a 1.5-inch flat stick or a 2-inch long cylinder.

Before hot surface ignitors and spark ignition was around, we had gas pilot lights that would stay lit burning a 1 to 2-inch flame year-round whether the heat was on or not. When the heat was turned on, the gas valve would flow more gas over the pilot to ignite the burner assembly that carried the flame.

So why do these silicon carbide igniters break so often? The fact is, a gas flame pours over these ignitors which applies a lot of damaging heat to them. The same thing that makes them work also destroys them!

Just today as I was called by one of my techs who said they accidentally broke an HSI as they were cleaning the burner assembly on a routine maintenance call. It happens. If you took your index finger and thumb and brought them together even somewhat quickly, that would be enough force to break the carbide tip of a hot surface igniter to pieces.

A heat exchanger that is overheated at shutdown could radiate extra heat on the ignitor to damage it or its ceramic base, especially in closed combustion systems like those Coleman or Intertherm downflow furnaces you find in modular and mobile homes. A fan cools the heat exchanger once the call for heat has been satisfied. Making sure the fan stays on for more than 90 seconds might be a way to correct this.

A gas furnace needs some type of system to ignite the gas or the combustion process cannot take place. Depending on the age of your gas furnace, the type of furnace ignitor may have been different. A very old furnace may still have a traditional pilot light and newer models may have a spark ignitor or a hot surface ignitor. In this article, we will take a closer look at furnace ignitors and how to clean them to improve performance and efficiency.

For most of the 20th century, the ignition was created with a standing pilot light. The pilot light would burn continuously with a trace quantity of gas and combustion could take place when required. The main drawback to this system was that if the pilot light went out, it would need to be relit before heat could be generated. At the end of the century, some manufacturers switched to a new ignition system that uses a spark ignitor. At first, the spark ignitor would light the pilot light, and eventually, they replaced them entirely. The modern variant is a hot surface ignitor that has a resistive heating element that warms up and glows red hot to cause combustion. 041b061a72
